Phylogenetic niche conservatism, phylogenetic signal and the relationship between phylogenetic relatedness and ecological similarity among species.
Ecologists are increasingly adopting an evolutionary perspective, and in recent years, the idea that closely related species are ecologically similar has become widespread. In this regard, phylogenetic signal must be distinguished from phylogenetic niche conservatism. Phylogenetic niche conservatism results when closely related species are more ecologically similar that would be expected based ...
متن کاملThe balance of ecological destruction and repair.
Ecological restoration has been receiving enormous attention in recent years. The National Research Council book Restoration of Aquatic Ecosystems: Science, Technology, and Public Policy (Washington, DC:National Academy Press, 1992) received substantial and widespread publicity from the news media on its release, as well as substantive attention from the scientific community. A new journal, Res...
متن کاملSynthesizing phylogenetic knowledge for ecological research
The demand for knowledge about the tree of life is steadily rising in ecology and other fields, but bioinformatic resources designed to meet these needs remain poorly developed. Ecologists pursuing phylogenetic insights into the organization of communities have come to rely on relatively conservative reference trees that, in general, are poorly resolved and documented. New methods for inferring...
متن کاملOptimizing Phylogenetic Diversity with Ecological Constraints
Given an edge-weighted tree T with leaf set X, define the weight of a subset S of X as the sum of the edge-weights of the minimal subtree of T connecting the elements in S. It is known that the problem of selecting subsets of X of a given size to maximize this weight can be solved using a greedy algorithm. This optimization problem arises in conservation biology where the weight is referred to ...
متن کاملPhylogenetic uncertainty revisited: Implications for ecological analyses.
Ecologists and biogeographers usually rely on a single phylogenetic tree to study evolutionary processes that affect macroecological patterns. This approach ignores the fact that each phylogenetic tree is a hypothesis about the evolutionary history of a clade, and cannot be directly observed in nature. Also, trees often leave out many extant species, or include missing species as polytomies bec...
